We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

You need to finish reading the article you posted. Some gems include that solar is now the cheapest electricity source in some sunny areas, that it's price continues to drop rapidly, and that if coal burning paid the real costs (including paying $50/ tonne for the carbon they put into our collective atmosphere) then photovoltaics would already be on par or cheaper throughout Germany (the source of the prices the article is quoting).

One day, robots will be ubiquitous: everywhere, all the time, helping in whatever ways are necessary. (Yes, I did read a lot of Isaac Asimov growing up. But it still seems inevitable.) Bipedal robots will be necessary, since our artificial world has been constructed for bipedal creatures between about 3' and 7' tall.

Japan's Asimo robot was a ridiculous dead-end: perfectly controlled to essentially run scripts over well-known terrain with virtually no uncertainty or randomness. A real bipedal walking robot will need uncertainty baked in from the very beginning, which Atlas clearly has from watching the video. It looks like a (slowed down, more clumsy) version of a person walking over uncertain terrain, if that person were blindfolded (which Atlas essential is in this demo, as it has no camera inputs). What you see as evidence of weakness is actually evidence of vast ability!

From these beginnings, you're going to see researchers add in more complex terrain coupled with video cameras input for prediction of foot-ground-interactions, and gradually increasing speed. Around the end of this decade (or perhaps the next), we will see bipedal robots able to work and move (including running) in and over highly variable natural terrain, and thus be truly useful in whatever situations they are required, thanks to the productive research direction pushed forward by Atlas. Yes, it will take some time, but this is one branch of artificial intelligence / machine learning, and as we have discovered in the field, the things that humans and living things find easy are actually incredibly *hard* to get robots / computers to do.

The author of exple.tive thinks that it's all about execution, efficiency, which his sources clearly indicate it's not -- but he's so hung up on execution efficiency being the most important thing in his mind that he doesn't even realize what his sources are saying.
It's actually all about ease of programming. The logic of offsets is easier to follow when indexing from zero. Full stop.
(That said, as others have mentioned, people still count from one.)
